In early 2021, heavy rains and strong winds toppled trees, causing the slope to collapse next to Rugg Road near the Hideaway Court intersection in the Damascus area. A retaining wall will be built at this location.

Temporary protective sheeting and plant seeding are in place until permanent repairs are constructed.

Why

To stabilize the slope next to Rugg Road.

Schedule

• Design: March 2021 - March 2022
• Construction: July 2024 - Oct. 2024

Traffic impacts

Building the retaining wall will require two temporary road closures. Rugg Road will close for 4 weeks to place the anchors and construct the wall facing. The road will then open to traffic for 3-4 weeks for the wall to settle properly. After this, the road will close for another 4 weeks to construct the final roadbed, add guardrail and pave the road.

Road closures are needed for the majority of construction. While the road closure schedule may need to be adjusted, the tentative plan is:  

• Road closed: July 8th to Aug. 11 
• Road open: Aug. 12 to Sept. 18 
• Road closed: Sept. 19 to Oct. 17

When a road closure is not necessary for construction, expect shoulder and lane closures with flaggers guiding vehicles daily through the work zone between 7 a.m. to 6 p.m., Monday through Friday. While we do not expect any weekend work, it may be needed depending on many factors. Local access to driveways will be maintained. Pedestrian access will be provided.

Stay In Touch

This technology infrastructure project will help connect ferry riders with information on the operating status of the ferry.

The project includes:

• Extending fiber optic cable to the ferry location to provide wireless connection to electronic signs
• Adding cameras at the ferry landings for images to be viewed on the website and ODOT TripCheck
• Upgrading signs with wireless and electrical connection to display both open and closed status at four locations, and adding a fifth sign on Territorial Road west of Hwy 99E
• Adding access to sign status through a phone app
• Transitioning to fare collection by credit card instead of cash

Project map

Current activities

Installing fiber optic cable to the ferry signals. The fiber optic cable will be connected to the county’s fiber network sometime in July 2024. 

Schedule

• Design: Dec. 2016 - March 2023
• Right of way: April 2018 - June 2023
• Construction: March 2023 - July 2024

Project impact on traffic

• No road closures are expected during construction, although there may be delays up to 20 minutes near Advance Road or the ferry boat landings.

Funding

• Estimated total project cost: $1 million 
• Funded through federal Ferry Boat Discretionary Funds matched with county road funds

Updated and enhanced curve warning signs will be installed on 18 rural county arterial and collector roads over 36 miles.

These safety improvements are expected to provide:

• 20–35% reduction in fatal and serious injury-causing crashes from adding curve warning signs 

The traffic safety team has assessed and determined proper curve advisory speeds to post along each road segment where curve warning signs will be installed along the following roads: 

• 232nd Drive
• Baker Road
• Beavercreek Road
• Borland Road
• Elk Road
• Feyrer Park Road
• Grahams Ferry Road
• Hayden Road
• Knights Bridge Road
• Ladd Hill Road
• Leland Road
• Lone Elder Road
• Macksburg Road
• Molalla Avenue
• Rosemount Road
• Tooze Road
• Wilsonville Road

For more information on curve warning signs, read the ODOT Fact Sheet on Updated Curve Warning Signs. 

Why

To provide a safer roadway for all users and to reduce crashes.

Funding

• Project estimate $250,000.
• Funding is provided from county road funds and HB 2017 gas taxes. 

Six radar speed feedback signs will be added to reduce the speed of travelers on Stafford Road, New Era Road and SE 282nd Ave. 

Radar signs will be installed at the following locations:

• SW Stafford Road 
  • Northbound: south of SW Schatz Road
  • Southbound: south of Mountain Road
• S New Era Road
  • Eastbound: west of S Central Point Road
  • Westbound: east Central Point Road 
• SE 282nd Ave
  • Northbound: north of OR 212
  • Southbound: north of OR 212

Why

To provide a safer roadway for all users by reducing vehicle speeds.

Funding

• Project estimate $500,000.
• Funding is provided from county road funds.

Two radar speed feedback signs were added to reduce the speed of travelers on Redland Road approaching the community of Redland. An eastbound radar sign was installed near Norman Road and a westbound radar sign was installed near S Anna Mae Lane.

Why

To provide a safer roadway for all users by reducing vehicle speeds.

Funding

• Project estimate $60,000.
• Funding is provided from the County Road Fund.

The intersection of SE 242nd Avenue and SE Borges Road is an intersection with high volumes of traffic crashes located in the Boring area. The project adjusted the intersection alignment and road grade. 

Construction plans Signing and striping plans

Why

To provide a safer roadway for all users and reduce traffic crashes and prevent vehicles from leaving the roadway at the intersection. 

Schedule

• Design: Sept. 2019 - March 2021
• Right of way: March 2019 - June 2019
• Construction: Aug. 2023 - Oct. 2023

Funding

• Project estimate $680,000
• Funding is provided from Damascus Road Funds

Heavy rains caused a portion of 232nd Dr. to sink and created large cracks in the pavement in the Barton area. The project will install a deep patch of pavement and improve drainage capacity.

Why

To ensure reliable connection to OR 224 and OR 212 and reduce ongoing maintenance costs.

Funding

• Project estimate $760,000.
• Funding is provided from Federal Highway Administration grant funds, County Road Funds and HB2017 state gas tax funding.

The intersection of King Road and SE 66th Ave. is an intersection with high volumes of traffic crashes located in the Milwaukie area. Traffic engineers studied the intersection and determined needs such as adding flashing lights at the crosswalk on the east side of the intersection, upgrading curb ramps to meet Americans with Disabilities Act standards and upgrading lighting. This project will be included in the Walk Bike Clackamas Plan and in the Transportation System Plan.  

Why

To provide a safer roadway for all users and reduce traffic crashes at the intersection.

Schedule

The county completed traffic safety analysis in Dec 2022. The analysis recommends constructing an enhanced crosswalk as funds become available.

Current activities

Analysis complete

The project will install a guardrail along 400 feet of Dryland Road between Heinz Road and Barnards Road at the curve.

Why
